Antibiotic Resistance: A Comprehensive Analysis
Statement of Purpose
The aim of this study is two-fold: 1. To provide an effective visualization that educates the general public about the dangers of excessive antibiotic use. 2. To offer infectious disease doctors a quick yet comprehensive overview of antibiotic resistance in commonly encountered bacteria.
Introduction
The following report aims to provide a detailed understanding of a dataset concerning antibiotic resistance across various bacterial species. This topic is of growing concern in the medical and scientific community.
Columns Explained
| Column | Description |
|---|---|
| Bacterium Name | Scientific name of the bacteria. |
| Causes | Diseases or conditions that the bacteria typically cause. |
| Gram-negative? | Indicates whether the bacterium is Gram-negative (‘yes’ or ‘no’). |
| Individual Drugs | Resistance levels to specific antibiotics, represented as percentages. |
| Remarks | Additional comments about antibiotic resistance. |
| Resistance Score | A scale from 1-4 indicating the level of concern, with higher scores being more concerning. |
| N Antibiotics or Classes | Number of antibiotics or classes showing at least some resistance. |
| Average % Resistance | Calculated average resistance score across all considered antibiotics. |
Key Highlights
Bacterial Species of Concern
- A. baumanii
- Nicknamed “Iraqibacter”
- High resistance to multiple antibiotics
- Resistance score: 4
- E. faecium
- 75% resistance to a specific antibiotic
- Average resistance: 47%
- N. gonorrhoeae
- Causes gonorrhea
- Resistance score: 3
- 14.35% average resistance
- M. tuberculosis
- Extremely drug-resistant variants
- Resistance score: 3
- S. aureus
- 25.90% average resistance but to only one antibiotic class
- Note After 1992
- No major new antibiotics have been developed for over 20 years.
- Gram-negative Bacteria
- Typically more resistant due to their cell wall structure.
Key Concerns
- Rising Resistance: Resistance is stable or increasing for many bacteria.
- Multi-drug Resistance: Resistance to multiple classes of antibiotics.
- Gram-negative Bacteria: More resistant and increasing so over time.
- Data Gaps: Unquantified resistances could underrepresent actual resistance levels.
Conclusion
This dataset serves as a snapshot that underlines the urgency for new antibiotics and effective strategies to manage antibiotic resistance. It calls for immediate action from both the medical community and policymakers.

Original
The original data visualisation selected for the assignment was as follows:
Objective and Audience
The objective and audience of the original data visualisation chosen can be summarised as follows:
Objective
Audience
Critique
The visualisation chosen had the following three main issues:
- hard for common audience with no medical background to identify issues
- blindness issues
- Preattentive Processing - Shapes and sizes of the circle is not unified (area is not obvious and overlapping on the grid), light/dark, use density mislead, Area (highlight timeline: no development new antibiotics for 20 years and the resistance of existing antibiotics) not compare on the same scale No major visually saying that no major new antibiotics develop in 20 years
Changes in new visualization: + Gestalt Laws: proximity (cluster together so a group?), similarity -> corrrect using symmetry to compare side by side, auto interpreted as the foreground (Figure Ground Principle) + Use Length to represent position - common scale - same scale but unaligned for 2 cat + Color - Hue (different color viz for nominal variables) + Use dodge method to have position adjustment. Other methods (filling, jiterring, nudging, stacking) + Faceting + Coordinate systems: Cartesian
data and aesthetic mappings,
• geometric objects,
• scales, and
• facet specification.
We have also touched on two other components:
• statistical transformations, and
• the coordinate system.Reconstruct

The following code was used to fix the issues identified in the original.

Data: In July 2014, the dataset on antibiotic resistance was sourced from informationisbeautiful.net. I have independently verified the integrity and accuracy of this data in 2023 against original sources, including the Centre for Disease Dynamics, World Health Organisation, and CDC (US data). Subsequent data processing and formatting to generate a tailored dataframe were conducted using the R programming language.

The antibiotics are also ordered based on their introduction dates, which can give an idea about the evolution of resistance over time.
